From award-winning author Sarah Prineas comes an all-new short story! This original thirty-page fantasy-adventure short story serves as a prequel to Winterling. Finn loves being a puck. He loves causing trouble, hanging out with his puck-brothers, and shifting from boy to dog to horse. There's nothing more fun! However, when Finn learns of the Mór's treacherous plan to get rid of the Lady of the Summerlands, will anyone believe him? And how far will he go to make sure it doesn't happen? Sarah Prineas is the author of the Magic Thief series and the Winterling trilogy (also composed of Summerkin and Moonkind).
